Filling head control

ABSTRACT

A filling head has a threaded piece which accepts a ring screw and a knurled piece about it. The knurled piece has an upper surface for engaging a flange of a nozzle, while the knurled piece has a bore to receive the nozzle. To control the filling head, the ring screw is first set, and then the knurled piece is screwed up securely to it.

4w 00 0 0 ihNOWOWQ MQ FILLING HEAD CONTROL The present invention is a head for dispensing liquids, and more particularly. one with an accurate level control.

In many industries it is necessary to dispense liquids into a container with a high degree of accuracy. A device which does, thus is known as a filling head. Typical prior art filling heads have a step adjusting mechanism which does not allow level control to a position intermediate the steps. Also, such heads must be able to withstand pressure from the liquid.

It is therefore an object of the present invention to provide a filling head control device that is highly accurate in its level control.

It is another object to provide such a device that can withstand considerable pressure from the liquid.

In brief, these and other objects are achieved by a bored and threaded piece about which a knurled piece and a ring screw are disposed. The ring screw is adjusted to set the desired level, and then the knurled piece is set to abut it. The upper surface of the knurled piece abuts a nozzle flange.

These and other objects, features, and advantages will become apparent from the description when taken in conjunction with the following drawings in which:

FIG. 1 is an exploded view of the invention;

FIG. 2 is a partly cross-sectional view of the assembled invention; and

FIG. 3 is a partly cross-sectional view of the invention receiving a nozzle and disposed above a container.

In FIG. 1 there is shown a body having an outer threaded surface 12, a smooth bore 14, and a lower flange 16 for engaging a container. A ring screw element 18 has a threaded inner surface 20 for engaging outer surface 12 and an outer knurled surface 22. A member 24 has a threaded longitudinal bore 26 for engaging surface 12, an outer knurled surface 28, and an upper surface 30 for abutting a flange on a nozzle.

FIG. 2 shows the components of FIG. 1 completely assembled. First the ring screw 18 is screwed onto body 10 and set to select a desired penetration depth of the nozzle into the container. Then member 24 is screwed onto body 10 until it is snug with ring 18. As shown in FIG. 2, surface 30 is flush with the top of body 10; however, this is not necessarily the case, which depends on the setting of ring 18.

FIG. 3 shows how the filling head of the invention cooperates with a bottle 32 and a nozzle 34. As can be seen, the nozzle 34 has a flange 36 that abuts the upper surface 30, which thereby determines the penetration of nozzle 34 into bore 14. If member 24 is higher on body 10, the penetration depth is smaller. Then the entire unit and nozzle 34 are lowered until flange I6 abuts container 32 as shown in dotted lines, and container 32 is filled.

It will be apparent that many variations are possible without departing from the spirit and scope of the invention.

Having herein described the invention, what is claimed as new is: v

l. A filling head control assembly for controlling the penetration depth of a nozzel :into an opening of a neck of a container, which comprises:

a. an annular flange affixed externally onto said nozzle;

b. a body having a threaded outer surface thereon and a longitudinal bore therethrough, said nozzle extending through said longitudinal bore;

c. a flange affixed to a lower end of said body, said lower end and said flange engaging said neck of said container;

d. a member having a threaded longitudinal bore therethrough adjustably engaging said threaded outer surface of said body, an upper portion of said member engaging said annular flange affixed onto nozzle; causing a lower end of said nozzle to be adjusted longitudinally within said neck of said container and e. a ring screw element having a threaded bore for adjustably engaging said threaded outer surface of said body, said ring screw element engaging said member.

2. An assembly as claimed in claim 1 wherein said threads comprise Acme threads to withstand pressure.

3. An assembly as claimed in claim I wherein said el- 4 wherein said
